Thisinvention relates to printingpresses and is concerned particularly with bed and -cyliiidertype of presses. The general ob-. 4ject is to provide a printing lpresswhich l5 shall operate rapidly Aand efficiently in whichA the'paper shallv be gripped without tearing andin which likelihood of damageV to any of theparts `or fouling from ink is provided aga-inst by the use of safety mechanisms. This includes effective mechanism vfor turning the platen to# active position only when paperis present, also an arrange- .meiitfwhereby the ductor roll of the ink mechanism does not function ifthe machin-e vis operated without paper, whether from neglect of; the operator or failure of the feed ing machine.

Further objects and featuresk of the invention `will become apparent from the .description of that embodiment of my invention illustrated in the accompanying` drawings, wherein I have shown a 'preferred form. Thev essentialV characteristics will besummarized inthe claims. y i

thev cam 72 the front end 95of the lever 90 willv be pressed downwardly intothe path of the notch 94. VJhen the Alever 90 is held in'its raised position with regard tothe plate 60 .by the auxiliary latching arm 92, it places the pin 107 in the path of the cam 72 so as to raise thevcam as it traverses the pin A107 as shown in Fig. 7. The pin 108 meanwhile'overlies the arm 75 tohold'the roller 74 in its position on the type bed. But if the lever 92 is tripped when the type bed is in its extreme rearward position, the pin 107 is withdrawn and the cam 72 dropsl to the position shown in Fig. 4.while the pin 108 no longer holds'the arm 75 in lowered position. It follows Y that the consequent return movementof the type bed will cause the arm 75 to be raised so as to lower the platen to printing position, where it will be held Yby the latch 90. i. f y

7, Ihave shown the relation of the pins to the cam`72 and the lever 7 5, where In Fig.

by the pin 108 serves as a safety device for retaining the platen in raisedposition'in respective oftheoperation of the spring 77.

at the point when the type bed is approaching its rearward position. '.VVhether paper is being fed, vthe cam may VVpass over itV on the return stroke of the typerbed. Now. if

for any reason the spring 77 shoul-dfail to act to hold the platen in raised positionand the lever 75 down, the roller 74 might engage the pointed .end ofthe cam and either suddenly stop the r machine or break the cam. Thisis eifectivelyprevented by the vpin 108 overlying the arm 75 sov long as 2the VYof Contact withtheplate, as shown in Fig. 2.

The. means for raising'the latch arm comprises a heel k114 on the lever-94 whichl is engaged by a lprojection 115 onv the plate when the roller 74 rides over the high point of the cam 72 or when the 'roller engages the high portion 85 of the cam 70, on either end 'of the stroke of the type bed'. -The exact cooperation of these parts will, belat'er set out more in detail.

Y Meansfor operating the latch `92 to acausel vthe' latch'90 to hold the impression platen in .lowered position-whenever asheetdof paper. isfed to themachine may comprise ay -foot' operated treadle such. as shown .in my priorapplication above referredto, orj a :5 paper 'controlled devices'uch as shown Ain the application ofHenry C.

The roller is'above the path of the paper.` to Vbe printed andY is adaptedv `to becarrie'd downwardly lintoV engagementtherewith by anarm' -131 rigidwith'the right handend of the shaft 122.- Thisl arm is actuated on every second revolution ofthe cylinder to move. the Vroller 129.into engagement withfthepaper rby reason of va,.tw o-to-one gearing, shown at 1132 and 133 onthe extremevrighthan-d-side of the. machine, ythegear,member, k132 Ybeing Arigid with Athe shaft 43,.',of the' cylinderlas shown in Fig. 3.- .The gearing acts tolfcause,

A feature of my invention is the 'mechanismlfor oiling the rollers 20 upon which the type bed rests as well as the bearing surfaces of the rails 18 and 21. I have heretofore experienced a great amount of difficulty in accomplishing this due to the fact that oilcannot readily be 4dammed inopen channels without causing waste, particularly where th-e channels are long and the rollers operate at a'moderately high speed. For examplev the oil becomes unfit for use by reason-of being exposed over a large area to dust in the airor it is Yspilled from the channels by the damming'efect of the mov- To eliminate these andother diflicultiesI have provided oil pick-up rollf shown in Figs. land 13. These rollers arev ers 265 on either end of. thetypebed as shown as Vsupported on arms 266 pivoted to the bearing'shafts 267 for the eXtreme rollers 20. When the chain of rollers is moved to either Vof its eXtreme positions, as the eX- `treme rearward position shown in Fig. l,

the rollers 265 dip into `oil reservoirs 268 supportedv on the frame l0.l Subsequently the rollers are carried along between the rails 18 and 20 to distribute oil thereto. The

vother rollers 20 pick up enough oil in traversing the rails to satisfactorily lubricate their bearings as well as their peripheral surfaces. Y v .Y
